-NAME
-----
-git-clone-pack - Clones a repository by receiving packed objects
-
-
-SYNOPSIS
---------
-'git-clone-pack' [--exec=<git-upload-pack>] [<host>:]<directory> [<head>...]
-
-DESCRIPTION
------------
-Clones a repository into the current repository by invoking
-'git-upload-pack', possibly on the remote host via ssh, in
-the named repository, and stores the sent pack in the local
-repository.
-
-OPTIONS
--------
---exec=<git-upload-pack>::
- Use this to specify the path to 'git-upload-pack' on the
- remote side, if it is not found on your $PATH.
- Installations of sshd ignore the user's environment
- setup scripts for login shells (e.g. .bash_profile) and
- your privately installed git may not be found on the system
- default $PATH. Another workaround suggested is to set
- up your $PATH in ".bashrc", but this flag is for people
- who do not want to pay the overhead for non-interactive
- shells by having a lean .bashrc file (they set most of
- the things up in .bash_profile).
-
-<host>::
- A remote host that houses the repository. When this
- part is specified, 'git-upload-pack' is invoked via
- ssh.
-
-<directory>::
- The repository to sync from.
-
-<head>...::
- The heads to update. This is relative to $GIT_DIR
- (e.g. "HEAD", "refs/heads/master"). When unspecified,
- all heads are updated to match the remote repository.
-+
-Usually all the refs from existing repository are stored
-under the same name in the new repository. Giving explicit
-<head> arguments instead writes the object names and refs to
-the standard output, just like get-fetch-pack does.

--quiet::
-q::
Operate quietly. This flag is passed to "rsync" and
- "git-clone-pack" commands when given.
+ "git-fetch-pack" commands when given.
-n::
No checkout of HEAD is performed after the clone is complete.
--upload-pack <upload-pack>::
-u <upload-pack>::
When given, and the repository to clone from is handled
- by 'git-clone-pack', '--exec=<upload-pack>' is passed to
+ by 'git-fetch-pack', '--exec=<upload-pack>' is passed to
the command to specify non-default path for the command
run on the other end.
SYNOPSIS
--------
-'git-read-tree' (<tree-ish> | [[-m [--aggressive]| --reset] [-u | -i]] <tree-ish1> [<tree-ish2> [<tree-ish3>]])
+'git-read-tree' (<tree-ish> | [[-m [--aggressive] | --reset | --prefix=<prefix>] [-u | -i]] <tree-ish1> [<tree-ish2> [<tree-ish3>]])
DESCRIPTION
* when both sides adds a path identically. The resolution
is to add that path.
+--prefix=<prefix>/::
+ Keep the current index contents, and read the contents
+ of named tree-ish under directory at `<prefix>`. The
+ original index file cannot have anything at the path
+ `<prefix>` itself, and have nothing in `<prefix>/`
+ directory. Note that the `<prefix>/` value must end
+ with a slash.
+
+
<tree-ish#>::
The id of the tree object(s) to be read/merged.
This command is usually not invoked directly by the end user.
The UI for the protocol is on the 'git-send-pack' side, and the
program pair is meant to be used to push updates to remote
-repository. For pull operations, see 'git-fetch-pack' and
-'git-clone-pack'.
+repository. For pull operations, see 'git-fetch-pack'.
The command allows for creation and fast forwarding of sha1 refs
(heads/tags) on the remote end (strictly speaking, it is the
List all variables set in .git/config.
+ENVIRONMENT
+-----------
+
+GIT_CONFIG::
+ Take the configuration from the given file instead of .git/config.
+
+GIT_CONFIG_LOCAL::
+ Currently the same as $GIT_CONFIG; when Git will support global
+ configuration files, this will cause it to take the configuration
+ from the global configuration file in addition to the given file.
+
+
EXAMPLE
-------
-------
The options available are:
+--bcc::
+ Specify a "Bcc:" value for each email.
+
+ The --bcc option must be repeated for each user you want on the bcc list.
+
--cc::
Specify a starting "Cc:" value for each email.
+ The --cc option must be repeated for each user you want on the cc list.
+
--chain-reply-to, --no-chain-reply-to::
If this is set, each email will be sent as a reply to the previous
email sent. If disabled with "--no-chain-reply-to", all emails after
Generally, this will be the upstream maintainer of the
project involved.
+ The --to option must be repeated for each user you want on the to list.
